Hello everyone, I have Thunderbird 45.3.0, I received an email with a pdf file and a p7m, but Thunderbird does not show me the pdf file, I tried to install add-ons ThunderPEC, DisableChunks and P7MON, but none of them solves the problem (which I later read that the bug has since been fixed internally to Thunderbird).

Chosen solution

is this a single file? Perhaps it is corrupted in some way. Virus scanning has been known to do this.
